To all concern:

, Be it known that-I, EDWARD E. GAnLrrs a citizen of the United States,and a resident of Turtle Creek, in the county of Allegheny and 'State ofPennsylvania, have invented a new and useful Improvement in Irons, oiwhich the following 1s aspecification.

ed .sad irons and pointed irons.

invention relates to electrically heatparticularly to double Oneobjectof my invention is to provide an electrically heated sad iron that shallhave reinforced terminal members forming an integral part of the heatingelement.

Another object of my invention, is to pro-.

vide an electrically heated sad iron that may be easily taken-apart andre-assembled.

Another object of my invention is to provide a sheet-metal unitaryterminal member 1 that shall be strong and durable construction. w o

Another object of my 1nvent1on 1s to provide-a positioning member thatshall be adapted to so hold the terminal members 'on that they need notbe secured to 'thehood ofthe iron.

' A further object of iiwention is to. provide an iron, of the aboveindlcat'e'd chariacter, that shall be simple. and inexpensive toconstruct and th'at shallhave its terminal memberslso disposed as toinsure uniform 'heatingthroughout and yet cause .the leading-interminals to be so placed at one s de of the handle as to impose as.little obstruction'to' the proper 'mampulatlon of the lron as j mible gn practising my invention, I provide a tary heating element having auniformly V distributed winding and unitary terminal members that extendfrom the center of'theheating element, a top plate having an o n ingtherein to permit the terminal mem is to extend toone side of the iron,a hood memberand means disposed between, the hood and the top inposition without securing them' to the hood. With this arrangement, theheating plate for so-positioningthe terminal members as to retain thesame p more.

parts-broken away of the top plate of the v iron shown in Fig. 1 andFig. 3 is a top plan view of the heating elementshown in Figs. -1 and 2.

Aniron embodying my invention comprises, in general, a double pointedbottom s ee amnomma Patent Patented Oct. 21, 1919. Application filedJune a, 1919. serial Ro.801,m4.

'my, invention; Fig. 2 is a top plan'view with plate 1, a unitary doublepointed heating j element-2, a top plate 3, a hood 4, a guide socket 5for the terminals of the iron and a handle member 6.

The unitary heating element 2, comprisesa metal bottom sheath 7, a,layer 8 of insulating material, a winding 9that is uniformly distributedthroughout to insure uniform distribution of heat, a second layer 10 ofinsulating material, two-plates 11 and 12 havmg portions thereofcut awayand so formed as.to' constitute receptacles 13 and 14, a layer 28 ofinsulating material and a top sheath 29. The conductors 15 from thew1nding 9 are secured to the plates 11 and 12 and the plates 11 and 12are insulated from the bottom sheath 7 the edges'of which are bent .overto so'retain the elements 7, 8, 9, 10, 11,

12, 13, 14, 28 and 29 in position as to constitute aunitary structure.

Threaded nippleslfi are secured in the receptacles 13 and 14 and receivethreaded re' movable bayonet contact members 17. The

portions 13 and 14 extend from substan- 18 in the top plate 3 of theiron. The open-: mg 18 extends from substantially the center of the Ironto one side'thereof. Since the tiallythe center of the element 2 and'ares0,* 1 shaped that they pass through an opening winding 9 is uniformlydistributed and the opening 18 extends from a central portion of themember 19, the iron will be uniformly 'heated and will thus have .nocold spots.

Portions of the layer 28 of insulating matenal are bent upwardly toprotect the mem-j here :13 and 14 as they pass thnough the opening 18.Screws 20 are provided for securing the element 2' and the top plate 19to the base plate I and screws 21 are provided for securing the hood 4:of the iron in position. The screws '21 are also adapted to secure thesaddle member 23 and the guide socket 5 in position. The handle 6 issecured to the saddle member 23 by a bolt or pin 24:.

An insulating member 25 having a shoulder 26 at one end to engage theopening in the hood 4: and an internal shoulder 27 to fit over thereceptacles l3 and 1a is disposed around the members 13, la and 17 andis so clamped between the top plate 3 and the hood t as to effectivelysupport the members 17 and to prevent withdrawing the same to break thelead conductors to the winding 9 when the iron is disconnected byremoving the plug connector (not shown).

From the above, it will be seen that it is unnecessary to secure themembers 17 to the hood and thus the iron may be easily taken apart andthe members 17 may be replaced without taking the iron apart. In orderto renew a heating element, it is only necessary to remove the screws 20and 21. This permits the hood 4k, and top plate19 to be removed and anew heating element inserted. Since the members 17 are di osed at oneside of the handle 6 interme iate the legs of the saddle 23, it will beseen that one of the chief difficulties of double pointed irons isremoved. That is, the connecting cord is at one side and, consequently,out of the Way. Heretofore, this was not feasible because if theterminals were brought through the top plate at one side, less materialwould obtain at that side and thus resuit in vcold spots. By my improvedconstruction, since the terminals are brought from the center oftheiron, the heat is distributed uniformly. 1

My invention is not limited to the specific structure illustrated, asvarious modifications may be made therein within the spirit and scope ofthe invention, as set forth in the appended claims.

I claim as my invention:

1. In an electrically heated sad iron, the combination with adouble-pointed bottom plate, of a double-pointed heating element havingits windings evenly distributed, and. a top plate having an openingtherein extending from the central portion of the bottom thereof to aside portion of the top to permit the leads to the heating element topass therethrough.

2. In an electrically heated said iron, the

combination with a double-pointed bottom plate, a double-pointed heatingelement, a top plate, and a hood member, of terminal members for theheating element integral therewith and passing through the top plate toa posltion adjacent the hood member, anda bushing disposed between thehood member and the top plate to secure the terminal members inposition.

In an electrically heated sad iron, the

combination with a double-pointed bottom' plate, a double-pointedheating element, a top plate, and a hood member, of terminal members forthe heating element integral therewith and passing through the to plateto the hood member, and a remova le insulating bushing disposed aroundthe termi- .nal members between the hood member and the top plate.

l. In an electrically heated said iron, the combination with a bottomplate, a heating element, a top plate, and a hood member, of terminalmembers for the heating element integral therewith and passing throughthe top plate, bayonet contact members secured to the terminal members,and means disposed around the terminal and the bayonet members andwedged between the hood and the top plate for securing the said membersin position with respect to the hood member where they pass through thetop plate.

In an electrically heated sad iron, the combination with a bottom plate,a heating element, a top plate, and a hood member, of a terminal memberfor the heating element integral therewith and passing through the topplate to one side of the hood members and a removable insulating memberso wedged between the hood member and the top plate as to secure theterminal member prising a terminal plate having portions thereof formedto constitute a receptacle, an internally-threaded member disposed inthe receptacle so formed and a screw-threaded bayonet contact memberdisposed in the threaded member.

8. A-heating element for a sad iron com prising a terminal plate havingintegral portions thereof formed to constitute a to: bular member, and acontact member. removably disposed inthe tubular member. 9. In anelectrically heated. sad iron, the combination with a double-pointedbottom plate, of a double-pointed unitary heating element having itsterminals at the center thereof, a uniformly distributed winding and aoop plate having an opening therein to permit theterminals from thecenter of the heating element to pass therethrough to a; position to oneside thereof.

10-. In an electrically heated sad iron, .the combination with adouble-pointed bottom plate, a double-pointed heating element, and

a handle, of a top-plate and a hood to the terminalsof the heatingelement to extend from the center of the heating element to a positionat one side of the handle.

11. In an electrically heated sad iron, the combination with a heatingelement, a top plate and a hood, of terminal members integral with theheating element and extending freely through the top plate'and the hood,and freely removable means wedged between the hoodand the top plate forsecuring the terminal members in position.
